An analysis of the article about creatine by chevreul

A French scientist, Michel-Eugene Chevreul, is credited as being the first to discover creatine in after extracting it from meat. Anyone taking creatine supplements for therapeutic or athletic purposes should do so under a doctor's care.

In addition, it seems that creatine can act as an effective antioxidant agent after more intense resistance training sessions. In a statue was erected to his memory in the museum with which he was connected for so many years.

As creatine is predominately present in the diet from meats, vegetarians have lower resting creatine concentrations [ 2 ]. The most popular formulation of creatine is creatine monohydrate, which is also the creatine formula that has been most extensively tested in clinical studies.

Since the majority of creatine is stored in skeletal muscle, dietary creatine supplementation has traditionally been important for athletes and bodybuilders to increase the power, strength, and mass of the skeletal muscle.

Creatine is used and researched in a clinical setting to investigate various pathologies or disorders such as myopathies [ 34 ] and is also used as an ergogenic aid for improving health and sports performance in athletes [ 5 ].

The available evidence indicates that creatine consumption is safe. A more recent in vitro study showed that creatine exerts direct antioxidant activity via a scavenging mechanism in oxidatively injured cultured mammalian cells [ 43 ].

Creatine can provide other neuroprotective benefits through stabilisation of mitochondrial membranes, stimulation of glutamate uptake into synaptic vesicles and balance of intracellular calcium homeostasis [ 72 ]. Creatine may also be a promising treatment for other types of physical rehabilitation.

It also minimizes muscle fatigue during contractions. Before discussing these alternatives, a background on the physiology of creatine supplementation will be given.

Super Supplement Feature: Are They Superior to Monohydrate?

For this short high-intensity exercise, creatine supplementation resulted in a 7. When the body is already demanding fluids to replace those naturally lost during physical activity, severe dehydration can be a very real danger. When creatine use was stopped, the animals lost the added weight.

Inresearchers at Harvard University found that ingesting creatine could dramatically boost the creatine content within the muscle. The specific aspects of anaerobic endurance performance improved by creatine supplementation were work and power, both of which had a mean ES greater than 0.

Privileged access to mitochondria of calcium influx through N-methyl-D-aspartate receptors.

Creatine: A Short History

The compound is a naturally occurring, non-essential amino acid found in red meat, pork, dairy products, and fish. Creatine has also been shown to be of some benefit in neurological and musculoskeletal diseases and conditions that involve muscle wasting or deterioration of muscle function, such as amyotrophic lateral sclerosis ALSmyasthenia gravismuscular dystrophyHuntington's disease, Parkinson's disease, and McArdle's disease.

Furthermore, response to creatine supplementation varies among individuals.

The authors suggested that the rise in muscle IGF-1 content in the creatine group could be due to the higher metabolic demand created by a more intensely performed training session.

Finally, although presently ingesting creatine as an oral supplement is considered safe and ethical, the perception of safety cannot be guaranteed, especially when administered for long period of time to different populations athletes, sedentary, patient, active, young or elderly.

The American College of Sports Medicine has estimated the national consumption of creatine in was 2, tons 2, metric tons.

One study, which looked at knee surgery patients in rehabilitation, found that subjects who received creatine intravenously during their recovery gained leg strength faster than those who did not.

In his analysis of a soap made from pig fat led to a year study of a variety of animal fats.

Michel Eugène Chevreul

In an excellent review of the trials that have been completed, a leading authority in creatine research, Dr. This dietary supplement can be acquired from food sources such as meat and fish, along with athlete supplement powders.

His research on the "magic pendulum", Dowsing rods and table-turning is revolutionary. InRae and colleagues questioned if creatine supplementation enhanced intelligence in healthy subjects Is creatine the one true ergogenic aid?

This practice is based on results of a clinical study published in the American Journal of Physiology, which reported that carbohydrate solutions increased uptake of creatine by skeletal muscle in study subjects.

The latter method may avoid some of the gastrointestinal distress and cramping that has been occasionally reported with loading doses. The possibility for new additional formulation such as tablets or capsules is interesting for its therapeutic application due to its attributed better dissolution kinetics and oral absorption compared to CM [ 63 ].

Whether this weight gain comes from water retention, an increase of lean body mass, or a combination of both has not been conclusively established.

A quantitative, comprehensive scientific summary and view of knowledge up to on the effects of creatine supplementation in athletes and active people was published in a citation review position paper by the International Society of Sports Nutrition[ 5 ].

Regular serum creatinine tests may be recommended for these individuals to monitor their kidney function.Sep 15,  · Creatine is excreted in the urine as creatinine with a daily turnover of 2 grams per day.

Although creatine supplementation results in reduced, but reversible natural creatine production, creatine supplementation appears to have few unwanted side effects Thus, creatine is an attractive dietary supplement for athletes.

Principles and history. Creatine is a derivative of the guanidinium cation. A cyclic form of creatine, called creatinine, exists in equilibrium with its tautomer and with creatine.

Creatine undergoes phosphorylation, by the action of creatine kinase to give phosphocreatine. The phosphate group is attached to an NH center of the creatine.

Michel-Eugène Chevreul

Creatine is an endogenous molecule that stores high-energy phosphate groups in the form of phosphocreatine (creatine phosphate). During periods of stress or strenuous exercise, phosphocreatine releases energy to aid cellular function.

Jul 20,  · A meta analysis showed individuals ingesting creatine, combined with resistance training, obtain on average +8% and +14% more performance on maximum (1RM) or endurance strength (maximal repetitions at a given percent of 1RM) respectively than the placebo groups.

However, contradicting studies have reported no effects of creatine supplementation on strength performance. Creatine was first identified in by French scientist and philosopher, Michel Eugene Chevreul, who named it after the Greek word for flesh, kreas.

Soon afterwards, a German scientist, Justus von Liebig helped promote a commercially available extract of meat, on the grounds that it would give the body strength for extra work.

Creatine is probably the most researched ergogenic aid on the market, with more than studies published about it. 72 Creatine is an intriguing supplement for athletes desiring gains in muscle mass because creatine itself is used in conjunction with phosphate by the muscle to supply energy for high-intensity, short-duration (≈10 seconds or.
